To minimize the damage of flower materials by forming a reticulate upper support, which can be detached and disassembled, on a main body and forming a reticulate lower support under the main body so as to simplify the preparation of a bouquet.

A reticulate upper support 1, which can be detached and disassembled, is installed on the main body 2. In order that the flower materials may cross with one another at one point between the upper/lower supports 1 and 3, the flower materials are inserted from on the support 1 through the mesh of the supports 1 and 3. One point where the flower materials cross with one another generated between the supports 1 and 3 are united and the upper support is disassembled. The completed bouquet is taken out from the main body 2. In order to disassemble the support 1, the mesh of the support 1 consists of a matter in the state of a cuttable thread such as fiber, rubber, and wire. After preparing the bouquet, the thread-like matter is cut to disassemble the support 1 without damaging the bouquet. A beautiful bouquet is prepared without breaking its form only by inserting flower materials by crossing like this.
